Muslimah said:Chrsitians worship 3 dieties God, human being & angel. Thus make it very complicated ......they claim that God is One but they associate partners with Him.
Correction. There is no angel in the concept of Trinity. The Holy Spirit is an angel in Islam but not in Christianity.
I think the point that's often missed is that the Trinity is not exactly a "concept of God" but how He expressed and revealed Himself to humanity. Father, Son and Holy Spirit all have the same identity. The Holy Spirit is not seen by all Christians as a separate entity. To some He/It is merely Spirit, which relates to the idea that God is Spirit. In a sense, then, the three names refer to concepts of three things that share the same identity.
As Christians we often emphasise a "threeness in the number of entities" but I think it's really a "threeness in terminology." If the Holy Spirit isn't a separate entity -- that God is Spirit, then God isn't essentially three. The Trinity could therefore be just a way of expressing our relationship with God.
Jesus may be seen by some be a part of God, but may be seen by others as one who shared His identity. By sharing God's identity, Jesus made it possible for people to encounter "God" in a place where God wouldn't normally be experienced. But perhaps what was most important was Jesus' role. Jesus lived in a time of judgmental legalism. It was a time when people were making religion impersonal and dehumanising.
Because religions represent God, and there has always been the possibility that religion could be made into something impersonal and dehumanising, they could infer that God Himself was impersonal -- that human existence could be degraded into a life where we have to follow rules to be accepted by God.
I'm thinking that most importantly, it is not separate teachings in a religion that conceptualise God. The whole, entire religion conceptualises God. A religion that has a concept of God is itself a concept of God. Even teachings that don't have anything directly to do with God still contribute to a concept of God. Anything that explains or defines the purpose of what God created is itself conceptualising God because it has something to say about God.
A lot of people may wonder about the purpose of a religion like Christianity. We're all speculating and coming up with theories. Christianity, I believe, was a declaration by God that He is indeed personal. In Christianity, Jesus was a demonstration of what a personal God was like. Christianity, then, is about a pursuit of a personal relationship with God.
The Holy Spirit, as I said, is not necessarily a separate entity, it merely may suggest that God is Spirit. So the Holy Spirit is not a separate deity.
Is Jesus a Deity? If Jesus had God's identity, then in a sense Jesus was inheriting the qualities of a Deity. You could say it was like God handing Jesus a Torch. That Torch could be seen as God's light in this world. The planets orbiting the sun don't shine with their own light. They reflect the sun's light. A Deity is like a star. God is like a star that shines light on the planets orbiting it. These planets reflect that star's light. You could say then that Jesus therefore inherits the identity of a Deity, but is not himself a Deity in his own right.
In that sense there's only one Deity in Christianity -- God, which Christianity calls the Father.
Our faith is often accused of dividing God into three, but I think that's a misunderstanding of Christianity. The problem is how we're often taught to approach Christianity, not Christianity itself.
There are, actually, two "Trinities" in "Christianity." There is the "Doctrine of the Trinity" that was formulated several centuries after Christ and there is the "Trinity" expressed in the New Testament. The "Doctrine of the Trinity" defines a "God in three." The "Trinity in the NT" does not define a "God in three." It does not even say anything about God being three in one. There is, certainly, a "Trinity" in the New Testament, but not one with which we are familiar. This "Trinity" was a Trinity of terminology -- the Father, Son and Holy Spirit.
But perhaps the point I'd like to say is that, "threeness in terminology in a concept of God" does not imply "threeness in God." It does, however, suggest that the terms used in that terminology are closely related to the concept of God.
At least for now, I could say that Father, Son and Holy Spirit are indeed One, but not in the number of entities involved. They are one in identity. By "one in identity" I do not mean "one in purpose," but "one" as in all those entities sharing the same essential qualities of character that they are essentially the same person appearing in multiple entities.
I think Christianity's reasoning is the idea that God putting His own identity in another being was to declare that a relationship with God is ultimately personal, that one can approach such a relationship in the same way as we do with other human beings. The idea is not to assign "human qualities" to God, but to declare that God is compatible with human beings and capable of making Himself understood in human terms.
So perhaps Jesus wasn't about "making God human" as some suggest, but declaring that "humans beings can understand God" and that "God is personable."
